Excerpts: Ochre-stained rocks have been found in the cave
Red-stained bones dug up in a cave in Israel are prompting researchers to
speculate that symbolic
thought emerged much earlier than they had believed. (?

02. Spread of Decisions in the Corporate Board Network , arXiv

Abstract: Boards of large corporations sharing some of their directors are
connected in complex
networks. Boards are responsible for corporations' long-term strategy and
are often involved in
decisions about a common topic related to the belief in economical growth
or recession.
We are interested in understanding under which conditions a large majority
of boards making a same
decision can emerge in the network. We present a model where board
directors are engaged in a
decision making dynamics based on "herd behavior". Boards influence each
other through shared
directors.
We find that imitation of colleagues and opinion bias due to the interlock
do not trigger an
avalanche of identical decisions over the board network, whereas the
information about interlocked
boards' decisions does. There is no need to invoke global public
information, nor external driving
forces.
This model provides a simple endogenous mechanism to explain the fact that
boards of the largest
corporations of a country can, in the span of a few months, take the same
decisions about general
topics.

03. Computational Intelligence in Economics and Finance: Carrying on the
Legacy of Herbert Simon ,
Information Sciences

Abstract: This is an editorial guide for the special issue on computational
intelligence (CI) in
economics and finance. A historical introduction to the background is
given. This research paradigm
is traced back to Herbert Simon, who, as a founder of artificial
intelligence, pioneered the
applications of AI to economics. The move from the classical AI to CI
indicates a continuation of
the legacy of Herbert Simon. Computational intelligence has proved to be a
constructive foundation
for economics. In responding to what Herbert Simon referred as procedural
rationality, our study of
bounded rationality has been enriched by bringing autonomous agents into
the economic analysis.

03.01. A Web-Based Investigation Of Human Market Interactions , Physica A

Abstract: The unprecedented access offered by the World Wide Web brings
with it the potential to
gather huge amounts of data on human activities. Here we exploit this by
using a toy model of
financial markets, the Minority Game, to investigate human speculative
trading behaviour and
information capacity. Hundreds of individuals have played a total of tens
of thousands of game
turns (...). In particular, our results indicate a transition in players'
decision-making, as the
markets become more difficult, between deductive behaviour making use of
short-term trends in the
market, and highly repetitive behaviour that ignores entirely the market
history (...).

Modelling

Abstract: Learning occurs in all stages of a fishery, in the entire fishing
career of a fisher, and
even within a single fishing trip. It is an important aspect of fleet
dynamics; failure to take it
into proper account biases results of population dynamics studies and
results of stock assessments.
In this paper, I introduce and slightly generalise three learning models
and derive a new one. I
use them to analyse data on the short-term learning behaviour of all
fishers as a group in the
fishery (...) to demonstrate their utilities.

04. Executive Personality Traits And Eating Behavior , Int. J. Neurosc.

Abstract: Eating disorders (...) commonly involve a dysregulation of
behavior (e.g., a lack or
excess of inhibition and impulsive eating patterns) that is suggestive of
prefrontal dysfunction.
Functional neuro-imaging studies show that prefrontal-subcortical systems
play a role in eating
behavior and appetite in healthy individuals, and that people with eating
disorders have altered
activity in these systems. There was also a positive association with
cognitive restraint of
eating, suggesting that increased compensatory behaviors follow
disinhibited eating. These
psychometric findings reinforce those of other methodologies, supporting a
role for prefrontal
systems in eating.

05. Mother of All Marsupials , Science Now

Excerpts: Last year, the fossil beds of Liaoning Province, China, yielded
the most primitive
placental mammal ever found. Now comes another record-breaker: the most
ancestral marsupial known,
in such good shape that even some of the fur is preserved. (? the
mouse-sized fossil will provide
a wealth of information on how the earliest marsupials evolved. (...).
At 125 million years, the new fossil--dubbed Sinodelphys szalayi--pushes
back the record of
marsupials by 15 million years. (Molecular data suggest that the group
could be as old as 190
million years.)

06. Distorting Limb Design For Dynamically Similar Locomotion ,
Alphagalileo & Proc. Biol. Sc.

Abstract: It is a general scientific principle that structures of the same
shape and material
composition, but different size, cannot function in the same way. This
applies to animals and
plants, as well as man-made structures. However, mammals of a wide range of
different sizes are
able to move in the same way. We show that this is possible due to
systematic changes or
'distortions' in shape that compensate for the constancy of musculoskeletal
tissue properties. From
the literature we identify the straight-legged posture of larger mammals as
a distortion that
allows mammals of different sizes to exhibit similar movement patterns.

07. Comparing Genomes Shows Split Between Chimps and People , NYTimes

Excerpts: By comparing the human genome with that of chimpanzees, people's
closest living relative,
scientists have identified a partial list of the genes that make people human.

They include genes for hearing and speech, genes that wire the developing
brain, genes for
detecting odors and genes that shape bone structure.(...)

Humans and chimps shared a joint ancestor as recently as five million years
ago. (? they would
understand the genetic basis of how people differ from chimps and, hence,
the essence of what makes
humans human.

07.01. Genome Scan Shows Human-Chimp Differences , Natue Science update

Excerpts: The human and chimp genomes are about 99.2% identical. In the
most important bits of the
genome, this figure rises to 99.5%. Yet Cargill and her colleagues believe
that they have seen the
fingerprint of evolution in these small DNA differences.
The researchers compared the sequences for more than 7,500 human,
chimpanzee and mouse genes,
compiled by the genome projects for each species. Matching the two primates
against the mouse
revealed whether chimp or man has changed most from the ancestral starting
point shared by the
three mammals.

07.02. Humans, Chimps Wear Different Genes , Science Now

Excerpts: In both chimps and humans, many genes involved in cell signaling
(? have undergone major
changes since the time of the species' last common ancestor 5 million years
ago. But the genes
didn't follow the same track in the two species, suggesting that they faced
different pressures
from natural selection. In humans, 27 of 48 olfactory proteins and three of
21 hearing proteins
showed significant accelerated change, whereas that was not true in the
chimp. In contrast, the
chimp's genes for mesoderm development and skeletal structure had changed more.

08. Understanding Cell Lineages as Complex Adaptive Systems , Blood Cells,
Molecules, and Diseases

Abstract: Stem cells may be considered complex reactive systems because of
their vast number in a
living system, their reactive nature, and the influence of local
environmental factors (such as the
state of neighboring cells, tissue matrix, stem cell physiological
processes) on their behavior. In
such systems, emergent global behavior arises through the multitude of
local interactions among the
cell agents. Approaching hematopoietic and other stem cell lineages from
this perspective have
critical ramifications on current thinking relating to the plasticity of
these lineage systems, the
modeling of stem cell systems, and the interpretation of clinical data
regarding many diseases
within such models.

Excerpts: Can an adult human cell be turned back to an embryonic state
without the need for
cloning? If so, ethical objections to personalized regenerative medicine
would be swept away. (?
The treasure in this case is a cell that will resemble an embryonic stem
(ES) cell, which can grow
into any type of tissue. This cellular alchemy might one day provide the
means to repair a failing
body with grafts that are derived from the patient's own cells ?and so

earlier this year. It could
lead to alternative ways to help infertile couples conceive by in vitro
fertilization. Such cells
could, for instance, help parents who have genetic defects to give birth to
normal children. (?

08.03. Stretching Changes Stem Cells' Fate , Natue Science update

Excerpts: Stretching stem cells can influence whether they turn into fat or
bone, say researchers.
This might partly explain why exercise strengthens the skeleton.
The group studied mesenchymal stem cells. These dwell in bone marrow and
can create new fat,
cartilage, muscle and bone. The scientists perched single cells on one of
two different
growth-enhancing carpets: either squares that gave cells room to stretch
out, or tiny dots that
reined them in.
Stretched cells were more likely to become bone cells, the group found;
huddled ones became fat.

Excerpts: Establishing and maintaining cell polarity is essential for a
wide range of biological
processes. This is particularly evident during cell migration when the
asymmetric distribution of
protrusion forces at the front and the contraction-retraction forces at the
rear drive cells
forward. (? A major question facing cell biologists is how the activity of
these three small
GTPases is localized within cells. (? an alternative mechanism is revealed
by Wang et al. (2) with
their demonstration that during cell migration Rho GTPase activity is
spatially restricted to the
rear of the cell (?.

Excerpts: Cell migration is a highly integrated multistep process that
orchestrates embryonic
morphogenesis; contributes to tissue repair and regeneration; and drives
disease progression in
cancer, mental retardation, atherosclerosis, and arthritis. The migrating
cell is highly polarized
with complex regulatory pathways that spatially and temporally integrate
its component processes.
This review describes the mechanisms underlying the major steps of
migration and the signaling
pathways that regulate them, and outlines recent advances investigating the
nature of polarity in
migrating cells and the pathways that establish it.

09.02. Developmental Biology: Long-Range Signalling By Touch , Nature

Excerpts: One of the best-known mechanisms involves the production and
release of signalling
proteins, which convey instructions over long distances about how cells
should behave and what they
should become. Information can also be exchanged through the direct contact
of cells with their
immediate neighbours. Nerve cells are specialized for communicating over
long distances by touch.
(...) they can send longer-distance signals that are still mediated by
direct contact. To do so,
the cells grow finger-like protrusions called filopodia. (? reveals a new
tool by which tissues
can be patterned during development.

Excerpts: Unlike most other structures in the adult brain, the hippocampus
is able to produce new
neurons (neurogenesis) throughout adult life as it contains a population of
neural stem cells. It
is believed that neurogenesis contributes to the primary task of the
hippocampus, that of
coordinating learning and memory. (? in a rat model of brain inflammation,
the ability of
hippocampal neural stem cells to generate new neurons is severely reduced.

authors were able to restore hippocampal neurogenesis by blocking
inflammation with indomethacin, a

He estimates that over time this activity laced the atmosphere with about
40 parts per million of

nearly 0.8 °„C of warming

15.01. Self-Assembled 'Nanorings' Could Boost Computer Memory , Purdue News

Excerpts:

cobalt nanoparticles
Download graphic - caption below







Wei's research team has found a way to create tiny magnetic rings from
particles made of cobalt.
The rings are much less than 100 nanometers across ?an important threshold
for the size-conscious
computer industry ?and can store magnetic information at room temperature.
Best of all, these
"nanorings" form all on their own, a process commonly known as self-assembly.(?
"The nanoparticles link up when they are brought close together. Normally
you might expect these to
form chains, but under the right conditions, the particles will assemble
into rings instead."

16. UN Summit Pledges Net For All , BBC News Online

Excerpts: A UN summit designed to shrink the technology gap between rich
and poor nations has ended
with agreement on lofty principles, but no commitments to practical
measures. (?
Delegates from some 175 governments meeting in Geneva agreed on the need to
take the net to the
millions of people currently offline.
But there were no pledges for cash to bankroll technology-related projects,
as some African
countries had demanded.
Delegates said the summit did succeed in alerting world leaders to the
importance of new technology
as a tool for development.

Excerpts:



The machine where it all started



As world leaders meet to consider the future of the internet, the man who
took it out of the lab
and into the mainstream took centre-stage.
At an event to mark the opening of the UN technology summit in Geneva, Tim
Berners-Lee was reunited
with the machine he used to invent the web.

With UN Secretary General Kofi Annan at his side, he used the world's first
web server to send an
e-mail to more than 80 schools worldwide.

17. Biopolitics In The EU And The U.S.: A Race To The Bottom Or Convergence
To The Top? , Int.
Studies Qtrly.

Abstract: This paper examines the circumstances under which economic
globalization has led (and not
led) to a convergence in the regulation of agricultural biotechnology in
the European Union (EU)
and the United States. While the EU has taken a precautionary approach to
regulating biotech
products, the U.S. has decided that these products are no different from
those made using more
traditional methods. These varying regulatory responses pose an interesting
puzzle (...). The paper
then examines why the U.S. biotechnology policy mode recently has shown
signs of gravitating toward
the EU model, signifying a potential for convergence to the top.

18. The Great Election Grab , The New Yorker

Excerpts: There is a sense of embarrassment about what has happened in
American politics,?(? "The
rules of decorum have fallen apart. Voters no longer choose members of the
House; the people who
draw the lines do. The court seems to think that something has to be
done.?The case could well
become the court's most important foray into the political process since
Bush v. Gore. As Ronald
Klain, a Democratic lawyer in election-law cases, puts it, "At stake in
this case is control of
Congress-nothing more, nothing less.?

18.01. Rigging Election Boundaries: When Does It Go Too Far? , Christian
Science Monitor

Excerpts: The basic allegation in Pennsylvania is that gerrymandering
undermines the concept of
majority rule: Why should Republicans win 12 of 19 congressional seats,
when 48 percent of the
state's registered voters are Democrats and 42 percent are registered
Republicans?

"It would be quixotic to attempt to bar state legislatures from considering
politics as they redraw
district lines," (?. "But when one political party guarantees itself a
solid majority of seats,
even if it wins only a minority of the votes, the Constitution must provide
a remedy."

18.02. Time To Draw The Line , NYTimes

Excerpts: (? gerrymandering can violate the Equal Protection Clause. (? In
the nearly two decades
since, the equal-protection problems raised by partisan gerrymandering have
increased because of
the growing partisanship of the line drawers, and the sophistication of the
computers they use.
(?
As the Supreme Court recognized in its one-person, one-vote line of cases,
the interests of the
voters in a fair and democratic process must be paramount. The American
promise of democracy will
be hollow if the House of Representatives virtually ceases to have
contested elections.

18.03. Russia: Voters Profess Little Or No Interest In Upcoming Duma Polls
, Radio Free Europe

Excerpts: Widespread reporting by Russian newspapers of political parties
allegedly "selling"
coveted spots on their candidate lists to rich businessmen has furthered
the perception that the
process is tainted and to a large extent predetermined, reinforcing the
feeling among average
voters that they have little chance to influence the outcome on 7 December.
Piontkovsky says many people recall Josef Stalin's cynical comment of some
70 years ago in this
regard: "Stalin said, as you remember: 'It's not important how they vote.
The important thing is
how we count the votes.'"

Excerpts: The campaign to cut off terrorist financing has seen some
high-profile successes and
arrests in recent months, and investigators are continuing to delve into a
complex network of
Islamic charities and organizations in Northern Virginia that they say may
have funneled money to
terrorist groups. (?
   But the efforts to trace terrorist financing have been marred at times
by turf wars between
agencies and occasional conflicts in mission. (?

either been let go or

aiding the Sept. 11
hijackers. (?
The judge acted after reviewing new evidence that Ramzi bin al-Shibh, (?,

cell knew about the
attacks before they happened. The judge said that while he had strong
doubts about the reliability
